SanDisk Ultra 256GB UHS-I MicroSD Card (SDSQUAC-256G-GN6MN) Review

For weeks, I’ve been putting the SanDisk Ultra 256GB UHS-I MicroSD Card (SDSQUAC-256G-GN6MN) through its paces. This review aims to give you a comprehensive look at its performance, ease of use, and overall value, based on my real-world experience.
The SanDisk Ultra boasts a compact design, making it easy to insert and remove from various devices. The advertised blazing transfer speeds were a key selling point, and I was eager to see how they performed in practice. The card’s compatibility with Android smartphones and tablets is a major plus for many users.
My testing involved transferring large files (4K video footage and high-resolution photos), and the read speeds were impressive, consistently reaching the advertised 120 MBps. However, the write speeds were noticeably slower than advertised (10 MBps vs. the claimed 150MB/s), which is a point worth noting. This impacted the time it took to transfer large amounts of data, though it was still manageable. The card proved reliable and stable throughout my testing, with no data corruption or errors.
I also tested the card’s performance in different applications, such as recording 4K video and playing demanding mobile games. In these scenarios, the card performed adequately, without any noticeable lag or stuttering. The large storage capacity proved invaluable, allowing me to store a vast library of media files without running out of space.
Pros:
- Large storage capacity (256GB)
- Fast read speeds (120MBps)
- Compact and easy to use
- Reliable performance
- Wide compatibility with Android devices
Cons:
- Write speeds significantly slower than advertised.
- The price point could be considered high for some users.
Overall, the SanDisk Ultra 256GB UHS-I MicroSD Card (SDSQUAC-256G-GN6MN) is a decent option for users needing extra storage for their Android devices. The fast read speeds are a significant benefit for quickly accessing files. However, the slower-than-advertised write speeds are a drawback. If write speed is a priority, you might want to consider other options. While not perfect, the reliability and large storage capacity make it a valuable asset for storing photos, videos, and other crucial files, making it a worthwhile purchase for many smartphone users.
